23.4
The DAC clock signal clocks the internal logic of the
Audio DAC module. The data sample rate of the Audio
DAC is an integer division of the rate of the DAC clock.
The DAC clock is generated via a clock divider circuit
that accepts an auxiliary clock from the auxiliary oscil-
lator. The divisor ratio is programmed by clock divider

bits (DACFDIV<6:0>) in the DAC Control register
(DAC1CON). The resulting DAC clock must not exceed
25.6 MHz. If lower sample rates are to be used, then
the DAC filter clock frequency may be reduced to
reduce power consumption. The DAC clock frequency
is 256 times the sampling frequency.
